Re: Using SQL UDF in SQLRPGLE program gets decimal data error

I right clicked on one function:

First tab:  General
Contains the following:
Description
Data returned to invoking statement, type, length, CCSID
And numerous other stuff like 'reads sql data'.

Second tab:  Parameters
Guess what this tells you.

Third tab:  External program
Here's your service program, module, subprocedure, or java method.

Thus this stuff has to be in those tables somewhere.

Rob:

Hmmm... guess I should've been more explicit. True enough that the
definition of a UDF itself can be found as you describe, but I was
wondering about the definitions within the UDF, the field/object
definition table, if you will.

In the case of this thread, the field definitions listed by the compiler
do not seem to match the behavior of the UDF.

Or were you saying that the field definitions are also available there and
I just haven't looked for them correctly?
